Different Types of Documentary:

• Fully narrated- An off screen voice over is used to make sense of the visuals and dominate there meaning e.g. natural history documentaries. The narrator always seems authorative "voice of god".
• Foley Artists create sound effects. 
• Mixed- These use a combination of interview, observation and narration to advance the arguement.
• Fly OnThe Wall- The camera is 'unseen' or 'ignored' and simply records every minute of real events as they happen. There is often no narration leaving audience to reach their own conclusions.
• Example: 'Terry Prattchet is from a french film movement 'Cinema Verite' which means 'Truth Cinema'.
• Self reflective- When the subject of the documentary acknowledges the presence of the camera and speaks directly to the documentary maker.
• Towie- These type of documentaries are a docusoap but scripted. They blur the boundary between fact and fiction.
• Docudrama- A re-enacment of events as though they have actually happened.
• Example: 'Crime Watch'.
• Docusoap- These documentaries follow the lives of individuals usually with designated occupations.
• Example: 'Airline'.
• 'The Only Way Is Essex and The Hills are examples of a docusoap but taken to the next level, they are sripted. This blurrs the lines between the documentary and soap.
